By kind of evidence
A day carried by a ground observation, a radar detection and a warning is attested three independent ways. A day carried by one kind from one source is one report. Each report below keeps its own source.

- Hail history and data
The day is on record. The report is what reached the roof.
Everything above is the record for the day: enough to know there was a storm, where it was reported and how large. None of it says what reached one roof.
Run the address and the same archive is searched at the property: each report's distance and bearing from the roof, the measured size, the sources by name, and the federal record each figure came from, in a document that states its own method. About a minute.
The next day of record
A storm day that enters the record in your territory can be sent within hours of its page: the date, how many independent sources carried it, and the link to the day.
The next day like this one, sent to your territory.
A territory is a set of states, or up to 5 places with 30 miles around each. An alert names the largest hail measured and the largest detected, kept apart; a weekly digest lists the last 7 days every Monday. Nothing is sent until a confirmation link is opened.
How this page is made
- What counted
- Every hail report in the archive filed on September 29, 2014, in any state, with wind and tornado reports counted beside it and the places ranked by the hail reports within 10 miles of each centre. A hail day is a calendar date with at least one report: four sources describing one storm are one afternoon of hail, not four.
- Measured and detected
- A report from a person or an instrument is measured. A radar-derived size is a detection and is marked as one, here and in every document we issue. The two are never added together.
- Severe
- A day counts as severe when its largest report reached 1.00″, the National Weather Service criterion. Smaller hail is still on the record, and still on this page.
- What this is not
- Reports are counted as the sources filed them, so a storm four sources describe is four reports on this page and one afternoon of hail on a place page. This page is the record for a day; it is not a report on any property, and it states no opinion about one.
- Terms used on this page
- Storm day, independent source, measured and detected: each term this page uses is defined in the glossary as the report prints it.
- The record
- Searched from 1996 to today. Compiled 24 August 2026 and rebuilt daily as the archive deepens. Records are reproduced as the federal sources published them. The coverage page states what the record holds, by kind and by year.
About this record
Everything here is reproduced from public federal and volunteer weather records, as the agencies and observer networks that publish them released it. Titan Weather compiles the record; it does not observe the weather, and it is not affiliated with any source it cites.
No archive holds everything. Storms cross places where nobody is standing, instruments and spotters cover some areas better than others, sources revise their records, and recent reports can take weeks to arrive and settle. Where this page shows nothing, nothing was found in the sources searched, within the period and area it states. That is not a finding that no weather occurred.
These pages describe the public record near a place or on a date. They do not establish what reached any particular property, and nothing here is insurance, legal or engineering advice.
- Settled or provisional
- Settled. The last national segment covering this day settled on August 24, 2026, and the figures above are drawn from the settled record.
